Details

A detailed documentation of these new capabilities, is available in the new version of LiteNode's documentation.

If you use an IDE that supports autocomplete, you'll see a brief description and example when using LiteNode's methods as well as a link to the method's documentation.
Rendering templates has been updated to be asynchronous.
IDs for heading tags in Markdown, addIdsToHeadings, has been fully integrated into SMP. Now you can just write {# my-id} and LiteNode will take care of it for you!
Properties can now be extracted from a single file, from multiple files in the same directory or from an array of files.
groupByMarkdownProperty helps in categorizing or organizing markdown files based on a specific frontmatter field.
paginateMarkdownFiles helps in displaying markdown files in a paginated format, useful for creating blogs or documentations.
generateTOC helps in creating a TOC for better navigation within documents.

Add JSDoc for all methods

Ingrate addIdsToHeadings into SMP. Ensure Markdown heading tags in code's blocks are not parsed to HTML.
Make extractMarkdownProperties async. Input can be array, folder or file.

Bump LiteNode to major version and publish.
